    As a forewarning to those using LVM, dm-crypt, and Samsung solid-state drives, this combination in some manner(s) may lead to data corruption if using the Linux 5.1 kernel.

    Linux FSTRIM/Discard is being too aggressive leading to data loss on certain setups, which at this point seem to be isolated to those using LVM and dm-crypt. The device mapper bug in Linux 5.1 is causing for blocks to be discarded wrongly or too much and that can lead to "massive data loss" issues.
